Single side workpiece processing |
摘要 |
A centrifugal workpiece processor for processing semiconductor wafers and similar workpieces includes a head which holds and spins the workpiece. The head includes a rotor having a gas system. Gas or air is sprayed or jetted from inlets in the rotor to create a rotational gas flow. The rotational gas flow causes pressure conditions which hold the edges of a first side of the workpiece against an angled annular surface on the rotor. The rotor and the workpiece rotate together. Guide pins adjacent to a perimeter may help to align the workpiece with the rotor. Outlets through the rotor allow gas to flow out of the rotor. |
